To all whom it may 00mm..-

Be it known that we, CHARLES F; HENRY and JOHN M. HULETT, citizens'ofthe United States, residing at Bel'videre. in the county of Boone and State of Illinois, have invented certain newand useful Improvements in Mechanical Movements and Bases Therefor, of which the following'is a'specification,ireference being had to the accompanying drawings and to the reference characters marked thereon, which form a part of this specification.

This inventi n relates to mechanical more m'ents and metal base therefor.

Among the objects of the invention are to produce a simple means for converting the rotary motion of a driving shaft into the reclprocatlng mot on 'of apivoted or rocking lever; to produce a gearing support which shall be in'one piece and in which all, or nearly all of ,the operating partsmay be. enclosed in a protecting casing and'to producea simple andieffectiv'e mechanism, support therefor, which may be assembled as p siti n in the machine location where it is to befused. 3 p j To these ends, our invention consists in the devices and combination of devices herein illustrated, described and .fpointed out in the appended claims.

In the drawings:

1 Fig. 1 is a side elevation, partly broken away, of a structure embodying our invention. H p

2 is a planv iew of a portion off the top of the structure. I p

Rig. 3jis a side elevation of the structure, looking from a planeat right angles to that from which Fig. '1' is viewed.

Fig. 4 is a top plan view, enlarged, of the gearing, and the casting on which it is mounted. x H g The invention is shown s applied to a washing machinestructureof the dolly or comprising a tub A. resting or table B, having vertical 1 and cross brace bars 2. It has ahin' ed lid 3 in which is :Inounted 'the'usf ual operating shaft 41, c ari'yin 'wit-hin the tub the dollyor agitator D, and having mounted upon itsupper end, outside the tub, aspur pinion 5 The shaft ljis given a "rotary movement, alternately in opposite directions upon a frame upport a unit andthen place'das a unit into' final,

by the reciprocationrof a rack bar 6, the teeth of which engage the pinion 5. P is a power shaft rotated from any suitable source of power (notshown), usually an electric motor. This shaft carries a spur pinion ,7 which meshes with and drives the spur gear 8 rotatably mounted in a'suitable bearing 9. on the casting 0..

Thelink10 18 connected at one end to a crank pin'll on the gear 8 and at its other end to one arm of. the rocking lever 12. The

other arm'of said lever is connected at 18 to the rack bar 6. The pinion? isprovided' with a vhub 14 having, a circumferential annular groove 15 adapted for engagement with a pin or projectingpart on the pivoted lever 16, thelatter being connected the link 17 to an operating lever L, The gear pinion 7, and hub 14 are splined at l8 and mayslide upon the shaft P when the lever L is moved, in order tojengageor disengage said pinion Withthe gene; Motion may be imparted also to thepower shaft P from the shaft 19 through thetransmittin'g bevel gears 20, 21, where an electric motor is not used, the shaft 19in such case being driven from a gasoline or other engine (not shown)- by belt and pulley.

pinion 7, the power shaft Pis provided 24, secured to a' support 25, wliich projects upwardly from the casting C. Upon the Intermediate th'e'bevel g'ear 2Q fandthe end of the stud shaft 24 is a spur pinion 26 which is enmesh with, a larger spurgear 27 The shaft 28 ismountedin suitablejournal bearings 29 in the castingC andcarries the gear 27. Averti cally disposedshaft 30 is rotatably secured to "the frame in'a suitable bearing 31 and the'shafts 28' and 30 are operatively connected by the bevel gears 32, 38, mounted upon said sha'fts28 'and 3O respectively, From thisshalft 80, any suita-,

ble machine, such as'a wringer. mechanism, may be operated.' k Thus, power being applied to rotate. the shaft P, the wringer-driving' shaft 30 will be operated through the gearing 22', 23, 26, 27, 32and 33, and thedriven machine, such as a wring'er' for example, will in turn'be thrown ,into' andout of motion by its'own start ing' and stopping mechanism, of which there'lare many standard and conventional types now on the market. Should the lever L have been shifted to throw the pinion 7 into mesh with the gear 8, motion will be also transmitted to the reciprocating rack 6 by the pinion 7, gear 8, crank 11, link 10 and rock bar 12. Should it be desired to operate the wringer mechanism and not at the same time operate the agitator or dolly l), the pinion T is thrown out of mesh with the gear 8. p

In the grouping of; gearing above described. it has been found necessary to make the casting C of the special form illustrated, desirable features of which we will now describe. I

The main part of the casting C is substantially a rectan ular. L-shaped frame, the side being provlded with the bearings 25, 29 and for the shafts 24, 28 and P respectively. The side 36 has a journal bearing 87 for the shaft 19, while its opposite, paral lel side 38 is extended outwardly at 39 to form a clearance recess for the gear 27. The side 40 is extended circularly at 41. to form clearance for the bevels 31 and 32 and this curved portion 41 is strengthened by a downwardly and hemispherical web member 4-2. The fulcrum 43 of the lever 16 is mounted on a projecting arm 44. The bearing, 9 is formed on the end of the arm 45. A brace 46 extends from the side 36 to the end of the arm 45. Strengthening ribs 47 are formed on the arms 44, and 46.

The casting is bolted to cross bars 48 of the frame by bolts 49. The top margins of the walls 34, 36, 38, 40 and 41 are offset to form conventional shoulder at 39, to receive the gear cover or top 51, shown in section in Figs. 1 and 3, which latter is bolted down to the casting C by the bolt 52. The interior of the casting C affords a convenient receptacle for a lubricant for the gears, and the cover 51 protects the gears and the lubricant from the accumulation of dust and dirt, and also prolongs the life of the lubricant.

It will be'manifest that the casting C presents the greatest strength where strength is required. and at the same time contains the minimum amount of metal; and its shape is such that it may be cast in a single piece or unit.

It will also be manifest that the various parts may be assembled upon the casting C in the shop and the whole, as a. unit, may then be set in juxtaposition upon the crossbars of the frame and bolted securely there to. This results in a great saving of time and considerably reduces manufacturing cost. After being secured in place by the bolts 49, the parts 16 and 17 connected, and the end of the link 10 secured to the crank pin 11, the Washing machine may be operated. The shaft 30 will, usually, be out between its ends so as to form a conventional slip-joint union, which will facilitate the installation of the device upon the washing machine frame.

It will be manifest that the shaft 24 may be a stud shaft secured by nuts, as shown, to the casting and bearing 25, the gears 23 and 26 turning loosely thereon, or that the bearing 25 may be the usual journal bearing and the shaft 24 rotate thereon, in which case the gears 23 and 26 will be keyed to the shaft 24 in a familiar manner to rotate therewith.
